HOLDER FOR A WELDERS BRUSH Filed Aug. 12, 1960 I INVENTOR. JACK CamusHanna? BY WILSON, SETTLE,Mcmwfkmc,

ATTORNE Y5 Unit tes This invention relates to a combined brush holderand chisel particularly adapted for the cleaning of welds.

In the fusing together of metal or alloys by a welding process,electrodes are consumed and they leave on the work a residue of metaland slag. It is desirable in order to present a sound weld that thisresidue and flux be chipped off and brushed away. To this end I haveinvented an improved combined brush and chisel holder, related to asimilar device as described and claimed in my earlier Letters Patentnumbered 2,368,988, issued February 6, 1945, and 2,786,221 issued March26, 1957.

By my present invention I have improved the tool disclosed in my earlierissued patents in several respects to make it stronger, sturdier andmore rigid, resulting in a tool which is more eflicient and more usefulto the person who uses it than similar tools heretofiore used.

Accordingly it is an important object of the present invention is toprovide a combination chipping chisel and brush holder affording astrong and rigid support for the brush holding member.

Another object of my invention is to provide an improved brush holdingmember which is strong and rigid and which, at the same time, affords asubstantial receptacle for the brush back by encasing it and maintainingit all around.

A further object resides in the provision of a substantially fullyenclosed channeled box surrounding the edges of a brush back to providea strong brush holding support which can be economically fabricated, andwherein a strong spring yieldingly and firmly holds the brush inassembled relation in the channelled box.

Yet another object of my invention is to provide a strong and rigidsupport between a handle and a brush holding box to insure the provisionof a tool capable of withstanding the repeated impact and shock loads towhich the tool is subjected in normal use.

Other objects and advantages of this invention will appear in thefollowing description and appended claims, reference being had to theaccompanying drawings forming a part of this specification wherein likereference characters designate corresponding parts throughout theseveral views.

FIG. 7 is a side elevational view of still another desirable embodimentof my invention.

FIG. 8 is a fragmentary sectional view taken substantially on the line8-8 of FIG. 7 looking in the direction of the arrows.

" atcnt ice Before explaining the present invention in detail, it is tobe understood that the invention is not limited in its application tothe details of construction and arrangement of parts illustrated in theaccompanying drawings, since the invention is capable of otherembodiments and of being practiced or carried out in various ways. Alsoit is to be understood that the phraseology or terminology employedherein is for the purpose of description and not of limitation.

Referring now in more detail to the embodiment of my inventionillustrated in FIGS. 1 and 2, the tool is shown to comprise a handle 1,which may be made of wood or of coiled wire or other suitable materialand having a rod-like shank 2 which projects into the chisel 3. A brushholding saddle 4 is mounted on shank 2 and includes a box-like sheetmetal construction having formed along its bottom a longitudinallyextending stiffening rib 5 preferably substantially centrally positionedthereon.

- The brush holding saddle 4 has at the outer end a riser 6 having itsextremity 7 turned back to overlie and engage and clamp the lower edgeof the brush back 8, which for example may be formed of wood, metal, orother suitable material. The inner end of the brush holding saddle 4carries a spring clip 9 which engages the lower edge of the brush back 8at its forward end to maintain the brush back in place in the saddle 4.The clip 9 is secured to the saddle 4 by inserting the hooked toot 9thereof through a hole 4 formed in the saddle; the resilient bias of theclip provides a positive retention force. The spring clip 9 may be priedopen by the use of any suitable tool such for example as the shank of ascrew driver to relieve the end of the brush so it may be freed from theholder at will, as described and claimed in my prior Letters Patent2,786,221. In my improved construction as disclosed herein the spring 9urges the brush back 8 firmly into the saddle 4; however, there is notendency for the saddle to open up at the outer end because the sidesslightly overlap the end and thereby restrain the end from opening, asmore clearly shown in FIG. 3.

For the purpose ct containing the brush back within the brush holdingsaddle 4, a pair of upturned wings or flanges 1t) and 10 are employedwhich extend the length of the saddle. This provides a brush holdingsaddle which is rigid and less subject to damage by rough usage orhandling. At the same time it provides a holding saddle which affords amore substantial support for the brush, and which maintains it moresecurely in place. The holding saddle is also inexpensive tomanufiacture because it is drawn from a simple sheet metal blank; insome instances it may be deemed expedient for economy of manufacture toemploy heavier stock and omit the stiffening rib 5.

- The outer end of the brush holding saddle 4 is preferably welded orotherwise rigidly secured to the end of the shank of the chisel 3, arigid construction being provided by reason of the fact that the end ofthe shank 2 of the handle is also fixed to the shank of the chisel 3.The juncture between the side walls 10 and 10 with the end wall 6 isbuilt up and reinforced to provide a rigid and strong end structure asshown in FIG. 3. The inner end of the brush holding saddle has adisc-like downturned guard 11. The rod-like shank 2 is inserted througha hole substantially in the center laterally of the guard, and the guardand the shank are welded together as shown in FIG. 4.

To provide a more rigid and strong structure capable of withstanding thesevere shock stresses to which the device is subjected, there isprovided a reinforcing bridge construction between the rod-like shank 2and the brush holding saddle 4 at a portion of the shank intermediatethe guard 11 and the chisel 3. To this end I provide the shank 2 with anarcuate bend -12 to bring the shank into contact with the bottom surfaceof the brush holding saddle. This bent portion 12 of the shank 2 and thebottom of the saddle are welded or otherwise securely fastened to oneanother as illustrated at 20 to provide a rigid structure. The arcuatebent portion 12 is preferably, but not necessarily, located at aposition substantially equidistant to the ends of the brush holdingsaddle. This provides a more rigid and more substantial support for thebrush holding saddle, making a better and more useful tool.

FIGS. 5 and 6 represent another embodiment of theimproved tool in whichthe rod-like shank 2 is substantially straight. The brackets 13 and 13'have their ends 14 and 14 welded or otherwise fastened to the rod-likeshank 2, and their other ends are provided with turned out Wings. 15 and15' bent substantially at right angles. These wings 15 and 15 are weldedor otherwise fastened to the bottom of the brush holding saddle 4.

With reference to the embodiment illustrated in FIGS. 7 and 8, it willbe noted that the tool is shown with a sup porting block 16 of metalinserted between the substantially straight shank 2 and the bottom ofthe brush holding saddle 4. This block is welded or otherwise fastenedto both the shank and the bottom of the brush holding saddle.

The fastening brackets of FIGS. 5 and 6, and the supporting block ofFIGS 7 and 8, may be inserted at any intermediate position between theouter and inner ends of the brush holding saddle, or they may extend thewhole length of the brush holding saddle without departing from thescope and spirit of the present invention.
